A250-ml glass bottle was filled with 242ml of water at 20°c and tightly capped. it was then left outdoor overnight, where the average temperature was -5°c. predict what would happen. the density of water at 20°c is 0.998g/cm^3 and that of ice at -5°c is 0.916g/cm^3.

The glass bottle will get crack.

Explanation:

Volume of the glass bottles,V = 250 mL

Density of water at 20°C  =

Mass of water in bottle = M

Volume of water at 20°C ,V' = 250 mL ()

V>V'

M = 239.096 g

Since mass remains constant, the mass of liquid water will be equal to mass of water when freezes

Density of ice at -5°C =

Volume of the ice at  -5°C= V''

V''>V>V'

As we can see that volume of water has expanded on freezing and exceeded the volume of the glass bottle. This expansion will result in breaking or cracking of a glass bottle.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
